<<...OLE_Obj...>> Eastern Range Operations Forecast Op Number: F7326 Issued: 6 Jun 03 (0700 EDT) Valid: 8 Jun 03 (2:05 p.m., 2:44 p.m. EDT) Vehicle/Payload: Delta II / MER-A Location: Pad 17-A Launch Weather Officer: Joel Tumbiolo Synoptic Discussion: Once again, no changes to current forecast reasoning. Subtropical ridge will be the dominant large scale feature in control, with a weak frontal boundary located over northern FL. This boundary will keep the low level high pressure ridge axis south of the area through mid next week. This will result in the continuation of south-southwesterly flow throughout the atmosphere. Moisture levels will remain high, and will provide the fuel for daily afternoon thunderstorms. Daytime heating, in addition to local sea and lake breezes will be the triggers for thunderstorm development. Main concerns during will be cumulus clouds and developing thunderstorms within in the vicinity of the launch pad/flight path.
